QUESTION
There are 200 students in the 7th class at Manchester Middle School. Of these students, 22% play football and 12% play baseball. Eight students play on both teams. What is the probability that a student plays either football or baseball?
30%
8 students is 4% of 200. So, ##22-4=18%## play only football, and ##12-4=8%## play only baseball, and 4% play both. So in total, ##18+4+8=30%## students play a sport (either one or two), so that's the probability asked for.
